Half of the total global population are using social media and produce a huge amount of user-generated content and interaction records on Facebook, Twitter, Instagram, YouTube, LinkedIn and so on. AI and machine learning techniques have been leveraged to understand the unprompted feelings, opinions and preference of users by analyzing their social expression and interactions. This talk will introduce the advantages brought by the AI-powered recommendation systems, from which we have benefited to have an easy discovery of the posts we like to see on our favorite social networks, the useful products to purchase online, the interesting places to visit, etc. The key is to understand users’ interests and needs by learning from their historically generated content and interactions. The talk will also introduce our study of sentiment variation during the outbreak of Covid-19 for knowing how people feel in pandemic. The results are from deep learning language processing models applied on 105+ million tweets and Weibo messages in six different languages on COVID-19 (covering English, Spanish, French, Italian, Arabic and Chinese).
